The technical solution of the utility model is: comprise corrosion-preventing and resistance-reducing grounding body and the electrode potential slider that is attached thereto; In the housing of electrode potential slider, the parallel circuits that discharging gap and impedance component are formed is housed, an end of this circuit is drawn by insulated conductor, and the other end of this circuit links to each other with the metal electrode body of corrosion-preventing and resistance-reducing grounding body.
The utility model compared with prior art has following advantage:
1. adopt the electrode potential slider, can make earth electrode not shadow noon facility such as steel pipe anticorrosion;
2. can avoid the introducing of Yin Putong earth electrode and reveal cathodic protection current, can not increase the burden of cathode protection device;
3. electrode potential is isolated physical efficiency release lightning current and static;
4. the electrode potential slider provides the grounding resistance measurement passage, and realizes exempting from demolition and maintenance;
5. low-resistance anticorrosion conductive non-metals material, copper conductive layer, graphite linings or the zinc conductive layer of the coating of metal electrode body exterior have played effect anticorrosion, that fall resistance, have protected metal to avoid corrosion;
6. corrosion-preventing and resistance-reducing grounding body itself has good antiseptic power, and can slowly discharge electrolyte, plays the effect of falling resistance;
7. auxiliary existing other grounding system does not influence its grounding system when strengthening its grounded capacity, the earth electrode that can be used as departments such as electric power system, communication is connected with ground network.
